Brenell Engineering Ltd. was a British manufacturer of audio electronics, in particular professional quality reel-to-reel tape decks.
The company was founded in 1947 by Robert Hahn and Peter Glazer, as a small precision engineering company based in Northington Street, Clerkenwell. In 1953 the company produced its first tape recorder and went on to become a leading manufacturer of bespoke tape decks, including multi-track studio machines.
After a series of financial setbacks, the company was formally dissolved in January 1984.
All of The Beatles had Brenell tape recorders installed in their homes. These were used to make various tape loops and other recordings that eventually found their way onto several Beatles recordings, such as Tomorrow Never Knows.
